Let's Face the Music and Die — Sandra Scoppettone

All is not well in the life of Greenwich Village P.I. Lauren Laurano. She and her lesbian lover are drifting apart. There's a psychopath watching her every move. And her friend Elissa has been accused of murdering her wealthy aunt.

Lauren knows better and sets out to prove Elissa's innocence. But it's a more perilous assignment than Lauren imagined, and she's soon forced to use resources she never knew she had--just to stay alive.
